A '''frag grenade''', also known as a '''hand grenade''', is a type of [[weapon]] that appears in [[dNetHack]], [[notdNetHack]], and [[notnotdNetHack]]. The frag grenade is a [[Item size (dNetHack)|small]] [[Future tech|futuristic]] [[projectile]] that uses the [[firearms]] [[skill]], and can be [[thrown]] manually or used as ammunition for [[Grenade launcher (dNetHack)|grenade launchers]] and the [[BFG]]. It has a [[Object materials (dNetHack)|default material]] of [[iron]] and appears as a '''green spheroid''' when [[Identification|unidentified]], or as a "[[spheroid]]" if the hero is [[blind]] or at a distance.

==Generation==
[[Anachrononaut]]s (including [[Android]]s) start each game with knowledge of the frag grenade's unidentified appearance.

Frag grenades are not randomly generated, though they can be found in [[bones]] and can only be [[wish]]ed for by [[Tourist/dNetHack|Tourists]]. They cannot be created by manual [[Smith (dNetHack)|smithing]] unless the hero is an Undead Hunter that knows their appearance.

Several frag grenades can be found on the [[Anachrononaut quest]]: A [[chest]] in the northeastern-most hall of the base on the Anachrononaut quest home level contains 8 stacks of frag grenades along with a grenade launcher; 11 stacks of frag grenades are each spread randomly around the locate level at level creation; 7 stacks of frag grenades are spread randomly around each of the lower filler levels at level creation; and 8 more stacks of frag grenades are each spread randomly around the goal level at level creation. These also appear on the [[Android quest]], though the chest only contains one guaranteed stack of frag grenades, with another stack that has a {{frac|2}} chance of generating in the chest.

[[Deep one (dNetHack)|Deep ones]] and [[Deeper one (dNetHack)|deeper ones]] generated in the future (i.e. the Anachrononaut quest and Android quest) have an effective {{frac|9}} chance of being [[generated with]] a stack of frag grenades.

==Description==
A frag grenade can be [[applied]] to arm it, and thrown grenades will automatically become armed—a cursed frag grenade has a {{frac|2}} of not arming properly in either case. Monsters will not apply a frag grenade to arm it, but will arm it in the process of throwing it at the [[hero]].

==Origin==
{{wikipedia|Grenade}}
{{wikipedia|Fragmentation (weaponry)}}
A grenade is a small explosive weapon that is typically thrown by hand (referred to as a "hand grenade"), and can also refer to a shell or other explosive projectile shot from the muzzle of a rifle or a grenade launcher. Grenades are often spherical, cylindrical, ovoid or truncated ovoid in shape, and are sized to fit the hand of an average-sized adult. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (high-explosive and stun grenades), chemical aerosols (smoke, gas and chemical grenades), fire (incendiary grenades) or a jet of molten metal (anti-tank grenades). Their outer casings are generally made of a hard synthetic material or steel, and are designed to rupture and fragment on detonation, sending out numerous fragments (shards and splinters) as fast-flying projectiles.

A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and an arming safety secured by a transport safety: the user removes the transport safety before throwing, and once the grenade leaves their hand the arming safety is released, allowing the striker to trigger a primer that ignites a fuze, or 'delay element'; the fuze then burns down to the detonator and explodes the main charge. Some grenades are mounted at the end of a handle, known as "stick grenades": the stick design provides leverage for throwing longer distances, but at the cost of additional weight and length, and a friction igniter inside the handle or on the top of the grenade head is used to initiate the fuze. Stick grenades have been considered obsolete by western countries since the Second World War and Cold War periods.

Fragmentation grenades (or "frag grenades") are common in armies, and are designed to disperse fragments and damage targets within both the lethal and injury radii. The body is generally made of a hard synthetic material or steel, which will provide some fragmentation as shards and splinters, though in modern grenades a pre-formed fragmentation matrix is often used, and may be spherical, cuboid, wire, or notched wire. The implementation of the frag grenade item in dNetHack and other variants conflates the frag grenade with the "high explosive" grenade: high explosive grenades are classified as offensive weapons and have a much smaller casualty radius compared to their maximum thrown distance, though the spread of fragments and fuze can extend far past that radius; their explosive power also relies more on concussive effects, making them best suited for throwing into confined spaces such as fortifications or buildings.

Based on the message given by a frag grenade exploding while underwater, the item may also be conflated with the concussion grenade: concussion grenades are often used as [[wikipedia:Depth charge|depth charges]] (underwater explosives) around boats and underwater targets, with some designed for use against enemy divers and frogmen, and kill or otherwise incapacitate the target by creating a lethal shock wave underwater.
